📦 VL53L4CD HAL Driver Library

HAL Driver Library for the VL53L4CD Time-of-Flight ranging sensor.

This driver has been developed to be hardware-independent. This way, the functions present in the core can be used as-is on any other microcontroller. The only functions that need to be adapted are those contained in the platform folder, as these are the ones that interface with and depend on the hardware. Currently, only the ESP32 implementation is available.

💡 Examples

To get started with the driver, check out the examples folder for practical usage references. This folder contains the following files for each available microcontroller:

• vl53l4cd_basic.c
• vl53l4cd_polling.c
• vl53l4cd_interrupt.c
• vl53l4cd_multiple_devices.c
